If you don't have a floppy drive:
Use the SATA CD drive when you install Windows.
Press F6 when prompted during installation - take the Windows disc out.
Insert the motherboard CD and see if you can load the SATA controller driver.
If the driver is accepted - put the Windows disc back and continue.
If that doesn't work:
Try this to create a slipstreamed XP disc with a SATA controller driver, service packs etc:
Download and run
XP-Iso-Builder.
Follow the instructions.
At the step "
Controller driver" (6/11) you can add the SATA driver - click
Add > find the folder where the SATA driver is located.
The driver has to be unzipped and there has to be a file named
txtsetup.oem included.
Next step > click "
Start integration".
An ISO file will be created. Burn it with, for example,
ImgBurn.
